<P>PROBLEM TO BE SOLVED: To obviate the necessity of attaching a return spring after having attached a brake pedal and a leg-power applying member to a vehicle, and besides the necessity of installing a structure for attaching the return spring to the vehicle. <P>SOLUTION: A return spring 3 is integrated together with a crevice part 4 and a spring stay 5 to a brake booster 2. Then, it is made possible to attach it to a vehicle in this state. Hereby, the return spring 3 is already attached merely by attaching an object, in which the return spring 3 is integrated together with the crevice part 4 and the spring stay 5 to the brake booster 2, to the vehicle, so that the return spring 3 need not be attached separately after attaching the brake booster 2 to the vehicle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
